Can firewood be too old?
I recently bought a half cord of firewood for casual fireplace use. Once I started using it, I found it didn't burn anywhere near as well as the firewood I'd bought the previous year, which seemed well cured and pretty much all oak. This wood is clearly old, the bark has fallen off a number of the split logs, and the logs are "dirty", i.e. there's bits of old bark, etc. on many of them. Also, while not an expert, some seem clearly to be oak, but others I recognize as black birch and others--who knows? What bothers me most is that the wood does not burn very well--it burns slowly and not very completely--I have to keep adding wood to keep the flames up. Can someone tell me what's going on here? I'm guessing I got the guy's "miscellaneous" pile that has been hanging around a long time.
